45' View angle makes for a MUCH more comfortable viewing position than other binoculars. Well built and much more portable than their 100mm version. Cloor is very good (semi APO). FOV is small but edge focus better than most. Near focus is not good, because importer readjusted to give maximum focus travel at infinity. Nebula filter available as an option. Retracting dew shild also included. Included 1/4 adaptor. Case is optional. Individual focus. No trouble splitting Mizar and SAO28738.

Wow, I purchased a pair in 2009 used and was initially impressed with the look of quality and design , even the case was top notch. Focusing proved to be quite a chore: just finding to right diopter and distance focus was time consuming. The eyepieces were friction fit and sometimes came out a little too easily. When I did get a look at the moon it was probably the best binocular view ever for me. Clear/sharp/chrisp view. The unit I has was slightly out of collumnation so I ended up selling. Well built and light but the focusing precision was a little too much for me. Thanks

I must say that not enough has been said about the huge advantages these binocs have over "non angled eyepiece" models, after about an hour of looking at those deepsky objects, I have to say that I'd take a non aching neck over a negligible quible about optics (fujinon's in mind).Great binocs, a must for anyone who believes that comfort is a major part of a great night's observing!

I recently purchased the Miyauchi 20x77 and have really enjoyed them. They are mounted on a Bogen 3233 tripod with the Bogen 3063 tripod head. The quality of the optics and overall craftsmanship is very high. Both oculars turn with smooth and consistent motion. I did not experience the dew shield problems as reported by other owners. While pointed at zenith, they remained in their extended position. I couldn't believe how easy it was hunting down Messier objects with this pair even without a finderscope. I can not stress the comfort of observing with the 45* angled oculars. The views are very sharp and contrasty. There is only the slightest hint of flaring on only the brightest stars, otherwise they resolve to pinpoints. There is only slight false color on the brightest stars and planets. But let's be realistic, a pair of 20x binoculars is hardly the appropriate instrument for planetary observing. Some of the recent objects viewed include: M3, M4, M5, M6, M8, M20, M27, M57, and M81 & M82 in the same FOV, that was awesome. The only negative comment is that the wallet took a serious heat round. But you get what you pay for, in this case quality. I'm very satisfied with my pair.

Must say that although these bino's aren't as sharp as my 16x70 fuji's, they beat them out in contrast. Performed brilliantly when used on light polluted skies, 45 deg eyepieces a MASSIVE MASSIVE plus . focussing poor at best in comparison.

Not as rugged as fuji's and seriouly lacking any kind of warranty. One word of warning here. be sure to THOUGHLY check these bino's before purchase as I've had to send 2 pairs back. First pair for a serious flaw plain as day, in the left prisim (Is there a quality control department at miyauchi?) the second pair for heavy overcoating of the optics (almost looked like a pair of those bino's with gimmicky coloured coatings!). this aside the pair I have now are a dream, with a real big bino feel about them.

Some colour fringing and not too sharp to the edge of field unfortunately.

These bino's are surprisingly easily hand held when resting elbows on a surface, easier for casual scanning than Fuji's.

I believe that these bino's (Provided that you get a good pair) are exelent value for money, and sit at the top with Fujinon's bino's.

In these times of growing light polution I believe that these bino''s have a good magnification -to- aperture ratio that provides exelent contrast, and cuts down a light poluted sky's surface brightness

impressive binocs; had the 100mm version and prefer the 77's; super on deep sky panning, even under suburban skies; have had no problem with the light shields slipping on my unit; very finely made and a good compliment to a high power telescope in an amateur's high-end collection. even critics have to agree, the Miyauchis are the best lookin' binoculars around.

Recently bought a used pair, ergonomically they are extremely nice. I have not experienced the loose lens shade problem that others report. Images are very nice. My only complaint is that focusing is a little too smooth and tends to slip so readjustment is frequent. Additionally there is flairing around stars if the focus is not precise. Otherwise I love these binoculars, the 45 degree prisms being a great convenience. They work very well on my Bogen 3036 tripod with 3063 fluid pan head.

Obviously from the first posting someone has had a good experience with these binoculars. This is my experience: They arrived in a silver box without any warrenty card, instructions for cleaning/care or even "another fine product made by...." that you would receive with a Tak or Nikon, etc. The dew shields will drop to the retracted position when pointed NEAR the zenith, and the lens covers will fall off and dew shields will drop to the extended position when carrying with the lens pointed down. The side mounting points are placed about 2" too far rearward which means they cannot be used with a yoke mount as the weight is all at the front end. The carrying handle is loose and you have the momentary impression these things are going to hit the ground everytime you pick them up. The interocular adjustment is workabable but a bit crude. Optically they are only fair. Lots of flare on stars, Jupitor is a long multicolored blob with strange colors whereas with the TAK 22x60's you can just see banding and color. Great idea with the 45 degree changable eyepieces but they need better mechanical engineering and quality control on the optics. Try first if you are considering these.

Binocs have a fairly narrow field, but are sharp almost to the edge. They do show color on bright objects, especially planets, but you are able to see through the color to some extent to see some detail. These binocs are designed for deep space scanning, Milky Way, Messier objects, etc. and excel for their purpose. The 45 degree eyepieces really make them a delight to use, and the option of 30x wide-field eyepieces give more detail with no lost of FOV. Recommended!

I ordered a pair but ended up returning them. I was not awed by the performance, especially for the price. Color correction for a "semi apo" design was fair at best (not as good as my Fuji 10x70 Polaris or Canon 10x30IS's). There is very noticable color fringing and you have to stay EXACTLY on axis or else it becomes really annoying. Eyecups won't fold down for eyeglass wearers. FOV is rather narrow. IPD adjustment has a lot of play and feels sloppy. Focusers are too smooth and slip easily. They do have a sharp field and the 45 degree eyepieces are convenient, but it seems as though Miyauchi was looking for an "entry level" big bino and cut a few to many corners, IMHO. I personally wouldn't recommend them.

These are incredible binocs! I had the pleasure of spending a few hours with a pair & I have to say they are some of the finest binoculars I've ever seen. The light throughput in these is great, which yield bright images that are sharp & very contrasty. Stars are tack sharp out to the field stop. The 45 degree view angle is a real plus for astronomical use.

The FOV in these is only 2.5 degrees & the exit pupil is only 3.85mm, both of which are small for binoculars. However, these aspects did not affect performance at all in my opinion. The views were breathtaking. I was in awe that a 20x77's under good conditions clearly showed four stars in the Orion trapezium, with the Orion E starting to show elongation. I enjoyed the views through these as much, if not more than through my 8" scope.

The only other binocs that I've seen come close to these are the 10x70 & 16x70 Fujinon FMT-SX (Polaris) series. I highly recommend the Miyauchi's to anyone wanting to purchase high quality large binoculars...they are well worth the extra $$!!!!!!!
